Export to PowerPoint format (PPT, PTTx compatible)

[benlec]

Description

We would like to offer the capacity to our user to export the presentation in a PPT/PPTx compatible format.
We are aware of the export to PDF but for some reasons, our users would like to customize the presentation outside of our App (based on Spectacle). User tipically use PowerPoint.
